A good Spy vs. Spy book. Almost felt realistic. So I don't know if it's a little non-fiction with some fiction. Could be that way. Either way, it was a good suspense.

I have read this twice 10 years ago. After I re-read it, I gave it to a friend. I was in the Navy at the time and it was during a deployment, so he appreciated the hand-me-down book. He also ended up liking the book too.
